【Abstract】 In order to study dynamics of engine valve-train,the test bed of engine valve motion test was developed with Lab VIEW software. This paper describes the theoretical basis of the construction of the experimental platform,the overall design of the experimental platform,the implementation of software and hardware,and the final experimental verification.The developed test system integrates signal conditioning,data acquisition,data analysis and management,and can collect real-time waveforms according to the acquisition frequency,time and channel set by the operator,thus effectively improving the flexibility and accuracy of the system. Because of its strong practicability,the test-bed has certain application value in teaching and scientific research and has been successfully applied to undergraduate practical teaching.更多还原
